BLE Signal Analysis
Walk a lap and you know whether BLE coverage is enough
Scans nearby BLE advertisers, ranks them by signal strength and records RSSI trends. Walk around with the device and you can map BLE coverage and blind spots.
Typically used for coverage surveys before deploying a BLE sensor network, or simply to confirm whether a device is actually advertising.

Key capabilities
RSSI ranking
Sorted by strength so the farthest and nearest devices are obvious.
Trend recording
Signal change over time for the same device is visible.
Walk-around survey
Scan while moving to map the coverage boundary quickly.
Low-power scanning
Enabled on demand rather than occupying the radio permanently.
Technical specs
Typical scenarios
BLE network planning
Confirm a gateway location covers every sensor.
Confirming a device exists
If you suspect a device is not advertising, one scan tells you.
